Some weird intermittent Amundsen DAB & rSAP issues

Been seeing some odd intermittent issues with Amundsen ICE in my 5 month old Superb SE Business and was wondering if anyone else has seen the same things before I notify the dealer (either waiting for the service or taking it in especially, depending on if it happens more frequently).....

DAB

Occasionally the DAB station being listened to drops out, then when attempt to retune, unit says ALL DAB stations are unavailable - doesn't matter which ensemble I choose, the icon that looks like a radio beacon with a line through it appears by every station - I know that it isn't the actual signal from the transmitter dropping out because it's happened whilst cleaning the car on my drive, and my DAB radio in the garage continues to receive the same station that just dropped out on the Amundsen. Usually ignition off - lock car - unlock and ignition on solves it but can be incredibly annoying when cruising on the motorway!

rSAP

Have successfully connected my Samsung Galaxy S5 to the Amundsen and enjoying the better signal etc. that the full remote SIM mode gives but on a 3 hour journey last week, the MaxiDot twice popped up with a message saying no longer connected to the phone - then when attempting to reconnect, get the message "connection not possible". Found that a restart of the phone enabled the connection to be re-established, only for an hour later, got the same message. Plus kind of defeats the object of being hands free, when you have to fiddle with the damn phone to reconnect...!
